Blackwell Family Elizabeth Blackwell From MacKenzie, MorellTelegraph Address "Phoniatros London" 19, Harley Street, Cavendish Square, W. Decr. 3 1889 Dear Madam, I do not consider that the removal of the whole thyroid gland is a justifiable operation but the removal of a part might sometimes be undertaken with advantage especially in cases of fibroid goitre. In cystic or in fibro-cystic disease the desired end can be attained very often by milder treatment such as puncture, injection etc. Whilst the latter method is almost free from danger the removal of a portion of the thyroid always involves some risk. I remain yours very faithfully, Morell MacKenzie
